한방 보혈제의 기본처방인 사물탕과 보기제의 기본 처방인 사군자탕의 방사선 조사 마우스에서의 방사선 방호 효과를 소장움 생존(고선량 방사선, 12 Gy), 조혈세포 생존(중간선량 방사선, 6.5 Gy), apoptosis 형성(저선량 방사선, 2 Gy) 실험법을 적용하여 관찰하였다. 방사선조사 전 사물탕투여군(경구투여: 음수 mL당 2 mg씩 7일간, 복강내주사: 마리당 1 mg씩 방사선 조사 24시간 전)에서 소장움의 생존이 증가되었으며 (방사선대조군: $38.48{\pm}4.34$, 복강내 주사군: $77.98{\pm}16.11$, P<0.005), endogenous spleen colony의 형성도 높게 나타났고(방사선대조군: $3.5{\pm}4$, 경구투여군: $10.7{\pm}7.730$, 복강내주사군: $8.667{\pm}5.244$, P<0.05), 소장움에서의 apoptotic cell의 발생율은 억제되었다(방사선대조군: $5.111{\pm}0.529$, 복강내주사군 $3.919{\pm}0.214$, P<0.01). 사군자탕 병행투여군에서는 이상의 실험에서 통계적으로 유의성 있는 효과는 없었다. 이상의 결과는 사물탕이 방사선방호 식품으로 활용될 수 있는 가능성을 제시하였으며, 각 구성약재 및 성분의 효과에 대한 연구가 계속되어야 할 것이다.

Abstract

In order to investigate the radioprotective effect of Si-Wu-Tang (Korean name: Sa-Mul-Tang), a kind of traditional Oriental medicine as a blood-building decoction (Oriental medical concept: Bu-Xie), and Si-Jun-Zi-Tang (Korean name: Sa-Gun-Ja-Tang), one of the widely used Oriental herbal medicines as an energy tonic (Chinese medical concept: Bu-Qi). the jejunal crypt survival, endogenous spleen colony formation, and apoptosis in jejunal crypt cells were observed in irradiated mice. Jejunal crypts were protected by Si-Wu-Tang pretreated both per os (2 mg/mL of drinking water for 7 days, p<0.05) and intraperitoneally (1 mg/head, single injection at 24 hours before irradiation). Si-Wu-Tang adminstration before irradiation(1 mg/head, single injection at 24 hours before irradiation) resulted in an increase of the formation of endogenous spleen colony (p<0.005). The frequency of radiation-induced apoptosis in intestinal crypt cells was also reduced by pretreatment of Si-Wu-Tang (p<0.01). However, the radioprotective effect of Si-Jun-Zi-Tang was not as significant as that of Si-Wu-Tang. These results suggest that Si-Wu-Tang may be a useful radioprotective food, especially since it is a relatively nontoxic natural product.
